A power control system and method thereof for power consumption. [Prior Art] In general, a satellite positioning service is required in an electronic device such as a vehicle or a personal digital assistant (PDA), and a global positioning system (G1〇bai p〇) must be installed. The siti〇n System; GPS) module navigation device performs the necessary signal transmission, reception and processing to obtain the coordinates of the current location and to perform navigation work. The Global Positioning System continuously transmits Gps signals through 24 or so man-made satellites operating in six orbits above the Earth. The navigation device can calculate the GPS signals transmitted by more than three satellites. The latitude, longitude, altitude, speed, direction of travel, etc. of the location. ❿ In addition, the above-mentioned navigation device receives GPS signals, and its receiving state is easily affected by the external environment (such as weather, surrounding buildings, etc.), and it is ensured that it can always be in good condition without the moon b. The increase in the number of free electrons in the thick 'cloud layer will cause interference to the GPS signal', causing the GPS signal received by the navigation device to be too low and affecting normal navigation. In addition, if you enter a tunnel, an underpass, etc., the GPS signal will be blocked, and the navigation device will not be able to receive the GPS signal from the satellite. However, at this time, the gpS module of the navigation device does not stop working because no GPS signal is received, so the navigation device does not receive the GPS signal or the GPS signal is too low due to the environmental factors mentioned above. The inability to complete the positioning operation will result in unnecessary waste of power. In order to solve the above problem, the current practice is to provide a controllable navigation device: a button for setting the working power on/off, so that the user can manually determine whether the navigation device receives the signal to turn the signal on or off. The working power of the navigation device, in this way, the user not only has to be busy with the work at hand (such as driving the vehicle), but also needs to spare part of the time to observe the strength of the receiving signal of the navigation device, so that the GPS signal is extremely weak. When the signal is not turned off, the working power of the GPS module is turned off in time. It is obviously inconvenient for the user to operate, and it is easy to be taken care of by human factors, and the working power of the GPS module needs to be turned off. At the moment, it is impossible to completely avoid unnecessary waste of the working power required by the Gps module, and more importantly, such an operation method is extremely dangerous due to distraction when driving the vehicle. First, in order to extend the operation time of the satellite navigation device, how to propose a kind of power control system and its method, can achieve the power saving effect before the additional human operation is required, which is the current technical problem to be solved.

Referring to Figure 1, there is shown a schematic diagram of the basic architecture of the power control system of the present invention applied to a navigation device. As shown, the power supply control system 10 of the present invention is applied to a navigation device to effectively control the power consumption of the navigation device 1 and the navigation device 1 includes at least a signal receiving group 1 such as an amplifier ( Amplifier) signal amplification module, Global Position System (GPS) module 13, and GPS power management module 14. The signal receiving module is configured to receive the GPS signal transmitted by the satellite and output the signal. The signal amplifying module 12 is configured to receive the (four) signal output by the signal receiving module u, and execute the GPS signal. Enlarged processing 'to amplify the weak milk signal' and then to output and output an effective GPS signal; the Gps module is configured to receive the effective mail number output by the signal amplification module 12 to perform positioning processing; the GPS power management The module 14 is configured to output a power management signal to provide working power to the GPS module 13, and the power management signal includes a power-off (〇ff) management signal, a power-on ((5) management signal, and a plurality of different power-on Frequency management signal. In addition, the power supply control system of the invention will be applied to the internal guidance of a moving object (such as a car, a ship, an aircraft, etc.). 0735 11 200941204 In a portable electronic device with a navigation device, such as a personal digital assistant (PersQnal, such as PDA), mobile phone or portable battery As shown in Fig. 1, the power control system 10 of the present invention further comprises: 'storage pull group 100, signal_selection module 1〇1, and processing module (10). The power control system 10 of the present invention is hereinafter. The storage module 100 is used to pre-store the first threshold value, the second threshold value smaller than the ❿th 槛 value, and the plurality of different RF signals (10) di〇requenCy; RF a plurality of performance parameter ranges, and a plurality of power-on frequency parameters corresponding to each of the performance parameter ranges and inversely proportional to the performance parameters included in each of the performance parameter ranges, wherein 'the first threshold value, the second threshold value, And the performance parameter is the carrier-to-noise ratio (C/N) of the radio frequency signal, and the carrier noise ratio is stronger than the radio frequency signal, and the higher the radio frequency signal is, the higher the radio frequency signal is. The stronger, the correspondingly, the electric start frequency can be set to be smaller. 'The stronger the RF signal is, the more the RF signal is supplied to the mode, and the working power supply can be relatively reduced, just according to the power-on frequency. Open and provide a working power It can be sourced from the GPS module. And processing "^, _牛' and S' when storing five different box frequency signal salt parameter ranges through the storage module, and corresponding to each of the performance parameter ranges: source, frequency parameter, for convenience of explanation, The five RF signal-numbered two-number ranges are graded from one to five, and the higher the level, the higher the performance parameter (ie, carrier-to-noise ratio) included in the range, 12]10735 200941204 f That is, the stronger the RF signal, correspondingly, the power-on frequency is pre-stored with a gradually decreasing trend corresponding to the performance parameter range of the -to-five level. Moreover, the first threshold value corresponds to the navigation device i is completely absent. : GPS signal receiving (using the power control system i of the present invention, then: ~ the power management signal is the power off management signal, detailed later) to the GPS signal receiving process, the GPS signal strength is sufficient for the Gps mode, and 13-bit critical carrier-to-noise ratio; and the second threshold is corresponding to the navigation device 1 continuously receiving enough GPS signals to be located (using the power control system i of the present invention) At this time, the power management signal is a non-power-off management signal, which is detailed later). In the process of receiving no GPS signal, the GPS signal strength is just unable to satisfy the critical carrier-to-noise ratio of the tracking and positioning of the GPS module 13; In this embodiment, the first threshold value is greater than the second threshold value, because the signal strength of the GPS signal that is sufficient for the location of the GPS signal is greater than the process of the Gps signal. The signal filtering module 101 is connected to the signal amplifying module 100 for receiving the valid GPS signal output by the signal amplifying module 100, and performing signal filtering processing on the effective GPS signal to obtain and output a corresponding correspondence. The performance parameter of the radio frequency signal (RF). The signal_selection module 101 can be, for example, a radio frequency detector (RF p(10) leaf Detector).
